Sorry, the usage output was being blocked. Typing the command without
any arguments should have printed the following information:
$ perl ./samples/DOMCount.pl
USAGE: ./samples/DOMCount.pl [-v=xxx][-n] file
Options:
-v=xxx Validation scheme [always | never | auto*]
-n Enable namespace processing. Defaults to off.
-s Enable schema processing. Defaults to off.
* = Default if not provided explicitly
Schema usage with Xerces is rather odd (I think):
1) You cannot use -v as this applies to the DOCTYPE, and with schemas
you are not likely to use a DOCTYPE
2) You must enable namespace parsing, otherwise none of the
schema-specific attributes will be recognized
So...
$ perl samples/DOMCount.pl -n -s samples/personal-schema.xml
samples/personal-schema.xml: (37 elems)
samples/personal-schema.xml: duration: 1 wallclock secs ( 0.07 usr + 0.00 sys =
0.07 CPU)
I will point out that if you are only looking for tools that will help
validate you XML files, you have no need for Xerces.pm, you can just
use the samples that come with Xerces-C. If, on the other hand, you're
going to develop your own Perl applications, I think Xerces.pm will
come in handy.
HTH,
jas.
